High Usage Charge

With record-setting heat this past summer, there was a greater demand for energy. Overall usage peaked as we turned to air conditioning and other devices to cool down. This substantial increase in energy use combined with summer pricing may have resulted in your bills having been higher than you’ve previously experienced. There are ways, however, that you can take control of the amount you pay. Take a look at the information below that will help you make informed decisions on how to avoid the High Usage Charge. It’s never too early to get ready for the next summer.

Update December 2018: We filed a request with the California Public Utilities Commission to allow us to remove the High Usage Charge from our pricing plans. Pending Commission approval, we hope to remove the charge by summer 2019. Please  read more about our request.

How much is it?

The High Usage Charge is a higher price per kilowatt-hour above tier 2.

Baseline Allowance

The Baseline Allowance is the amount of energy required to cover your basic household needs such as lighting, cooking, heating and refrigeration. Your individual baseline is reviewed and approved by the State of California and is determined by your climate zone, season number of days in your billing cycle and whether you’re a gas-only or gas and electric customer.

How does knowing your baseline allowance help you avoid the High Usage Charge? The purpose of the High Usage Charge is to encourage energy conservation. This state-mandated charge only impacts you if your household exceed 400% of your baseline allowance. This is similar to how the data plan for your mobile phone works, where you're charged more for data use in excess of your allocated data. Knowing your baseline and managing when and how much energy you use may result in lowering your energy bills.

It depends on several factors, such as high temperatures. Typically, there are about 100,000 customers in the region that will reach this level of electricity use one or more times in a year. There are about 1.3 million residential customers overall, so this is slightly less than 10% of all customers.

Consider Solar
